Power of Siberia deal: What is the key energy link between Russia and China?

The EU's cheap-gas lifeline is being diverted to Beijing instead. Last September, Russia, China and Mongolia rerouted half a century of energy history eastward.

The three countries signed a legally binding memorandum for the Power of Siberia 2 pipeline – a roughly 2,600-km line, at an estimated cost of around $13.6 bn, that will carry 50 billion cubic meters (bcm) of natural gas every year through Mongolia into northern China's industrial heartland.
